عنوان انگلیسی DFT Study on the Carcinogenicity of some Common Polycyclic Aromatic Hydrocarbons (PAH)
چکیده انگلیسی مقاله Quantum mechanical study on the interaction between carcinogens and DNA nucleobase is an exciting and significant aspect in cancer research. Common aromatic carcinogens like; β-napthylamine, α-benzopyrone, phthalazine, quinoline, α-naphthol and β-naphthol; comfortably interact with DNA nucleobases (i.e., A, T, G, C, AT & GC) and it happens due to the effective π-π stacking interactions. In general, such type of interaction occurs through intercalation mechanism which takes place via π-stacking and results in very strong interaction with DNA nucleobases. In our case, all the carcinogen-DNA base pair stacked models have been investigated using density functional theory (DFT) method; as it theoretically helps to predict the proper molecular interaction and selectivity of carcinogens with DNA base pairs. Herein, computational calculations have been carried out to analyse the carcinogenicity of some common polycyclic aromatic hydrocarbons (PAH); and study reveals that β-naphthylamine (BNA) is highly GC-specific than that of other aromatic carcinogens. Hence, BNA shows higher carcinogenic or toxic effect on the DNA nucleobase than other selected carcinogens. On the other hand, carcinogens like quinoline (QUN) and phthalazine (PHZ) result in the least carcinogenic effect towards AT and GC base pairs of DNA nucleobases.
